when you do the subtraction 4126-2487, you regroup 1 thousand to 10 hundreds. does that give you 11 hundreds. explain

In order to explain the regrouping process in subtraction, let's break down the example you provided: 4126 - 2487.

When subtracting two numbers, we start from the rightmost place value and move towards the left. In this case, we begin subtracting the ones place: 6 minus 7. However, since 6 is smaller than 7, we can't subtract directly. To resolve this, we need to borrow or regroup from the tens place.

To regroup from the tens place, we change the 1 ten into 10 ones. This increases the number of ones available for subtraction. We then subtract the borrowed amount of one from the original number, which becomes 11 ones.

Next, we move to the tens place and perform the subtraction: 1 (borrowed) minus 8. Since 1 is smaller than 8, we need to borrow or regroup again from the hundreds place.

We change 1 hundred into 10 tens (or 100 ones) and add this to the tens place, making it 11 tens. We decrease the hundreds place value by 1, changing it from 4 to 3.

Finally, we perform the subtraction in the hundreds place: 3 minus 2, which results in 1.

Consequently, the answer to 4126 - 2487 is 1639.
